Preferred embodiments of the invention comprise an automatic reel capable assisting a user when attempting to unspool a linear material, such as a water hose. Each of the access points extracts performance data, for each message received from the at least first station, from the radio signaling. The direct current setting unit adjusts a direct current setting of the equalizer according to a plurality of direct current terms inputted by the oversampling logic unit within a first predetermined time. At the zero setting, a connector seating annular surface on the inner skewed bushing is disposed at a right angle relative to a cylindrical outer surface of the outer skewed bushing.
